Abstrakt: In this paper, we report on a pressure sensor based on graphene aerogel functionalized with SnO2 or GaN thin films deposited by magnetron sputtering. Decoration by nanocrystalline SnO2 or GaN was found to enhance the piezoresistive response of the bare aerogel. The responsivity and pressure sensing range (from 1–5 atm) of the sensor are shown to be higher than those inherent in pressure sensors based on graphene membranes. [ABSTRACT FROM AUTHOR]
